Description
Es ist bereits vorgeschlagen worden, bei Kipprelais mit zwei Schaltspulen und mehreren Kontaktträgern, die nach Überschreiten einer labilen Gleichgewichtslage selbsttätig in die neue Schaltstellung geführt werden, die Kontaktträger um einen Punkt des Ankers beweglich anzuordnen, der bei Bewegung des Anker? seine Lage ändert.It has already been proposed in the case of toggle relays with two switching coils and several Contact carriers that automatically move into the new switching position are performed, the contact carrier can be moved around a point on the armature to arrange the movement of the anchor? changes its position.
Um die Öffnung des Erregerkreises derjenigen Schaltspule, welche den Schaltlagenwechsel hervorgerufen hat, zu bewirken, tritt gemäß der Erfindung bei einem solchen Relais an Stelle eines dieser Kontaktträger ein Hilfsglied, das erst bei Erreichen seiner Endlage den Erregerkreis der genannten Schaltspule öffnet. Das bietet den Vorteil, daß ein starkes Zurückprallen des Ankersystems vermieden wird. Es sind zwar Kipprelais bekannt, bei denen nach Überschreiten der labilen Gleichgewichtslage die Schaltspule unterbrochen wird, welche den Schaltlagenwechsel hervorgerufen hat. Bei dieser bekannten Anordnung ist aber ■ ein besonderes Hilfsglied vorgesehen, das mit den zur Steuerung von Stromkreisen dienenden Kontakten über Zug- bzw. Schubstangen und Federn verbunden ist. Dadurch wird der Aufbau des Relais umständlich. Bei der Anordnung nach der Erfindung wird dieser Nachteil vermieden. To open the excitation circuit of the switching coil that changes the switching position has caused to cause occurs according to the invention in such a relay an auxiliary link in place of one of these contact carriers, only when it reaches its end position does the excitation circuit of said switching coil opens. This has the advantage that a strong rebound of the anchor system is avoided will. Although toggle relays are known in which the unstable equilibrium position is exceeded the switching coil which caused the switching position change is interrupted. In this known arrangement, however, ■ a special auxiliary member is provided, which is used with the control of circuits Contacts is connected via pull or push rods and springs. This will build up of the relay cumbersome. In the arrangement according to the invention, this disadvantage is avoided.
In der Figur ist ein Ausführungsbeispiel der Erfindung dargestellt. 102 und 103 sind die beiden Schaltspulen des Relais, 104 das Ankersystem. Um den Anker drehbar beweglich sind die Arme 106 und 107, welche durch die Feder 116 miteinander verbunden sind. Die Lage des Drehpunktes 105 und die Lage der Angriffspunkte der Feder 116 sind so gewählt, daß die Arme nach Überschreiten einer labilen Gleichgewichtslage sprungartig in die neue Schaltstellung geführt werden. Das bewegliche System 104 legt sich in der einen Schaltstellung an die Feder 108, in der anderen Schaltstellung an die Feder 109 an. Die Federn 108 und 109 sind so gewählt, daß sie in der Mittellage des Ankersystems entspannt sind, während in jeder Endlage des Ankersystems die entsprechende Feder soweit gespannt ist, daß sie auf den Anker eine Kraft ausübt, die etwas geringer ist als die durch die Kippfeder 116 ausgeübte Kraft. Durch diese beiden Federn wird erreicht, daß der Eigenbedarf des Relais weitgehend herabgesetzt werden kann. Der Arm 116 trägt den Kontakt 113, der sich in der einen Schaltstellung an den feststehenden Kontakt 114, in der anderen an den feststehenden Kontakt 115 anlegt.In the figure, an embodiment of the invention is shown. 102 and 103 are the two switching coils of the relay, 104 the armature system. Can be rotated around the armature are the arms 106 and 107, which are connected to one another by the spring 116. the The position of the pivot point 105 and the position of the points of application of the spring 116 are selected so that that the arms jump into the new one after crossing an unstable equilibrium position Switch position are performed. The movable system 104 is in the one switching position to the spring 108, in the other switching position to the spring 109. The springs 108 and 109 are chosen so that they are relaxed in the central position of the anchor system, while in each End position of the anchor system the corresponding spring is tensioned to such an extent that it touches the anchor exerts a force that is slightly less than the force exerted by the toggle spring 116. By these two springs it is achieved that the internal requirement of the relay is largely reduced can be. The arm 116 carries the contact 113, which is in one switch position on the fixed contact 114, in the other applied to the fixed contact 115.
Die Schaltspule 102 ist über den Kontakt 110 mit der Batterie 119, die Schaltspule 103 über den Kontakt 111 mit der Batterie 119 verbunden. 117 und 118 sind Schalter, die zum Einschalten der Schaltspule 102 bzw. 103 dienen. Die Kontakte 110 und in werden durch den Arm 107 des Kippschalters gesteuert. Dieser trägt ein Isolierstück 112 und öffnet nach Beendigung seiner Kippbewegung den Kontakt,The switching coil 102 is via the contact 110 with the battery 119, the switching coil 103 over the contact 111 is connected to the battery 119. 117 and 118 are switches for Switching on the switching coil 102 or 103 are used. Contacts 110 and in are through the Arm 107 of the toggle switch is controlled. This carries an insulating piece 112 and opens after Termination of his tilting movement,

Of the The armature will only carry out a small pendulum movement, since the pulling force of the switching coil almost continues until the armature movement has ended is effective.
An Stelle des in der Figur dargestellten Kippsystems, das aus den zwei Armen und der Feder 116 besteht, kann man auch das Kippsystem in anderer Weise ausbilden. Beispielsweise kann man einen Gelenkkopf verwenden, welcher an Stelle des Mittelstückes des Ankers 104 tritt, in dem am Umfang verteilt eine Reihe Arme gelenkig eingesetzt sind. Die Arme tragen, ähnlich wie der Arm 106, Kontakte, während einer der Arme wie der Arm 107 ausgebildet ist. An Stelle der in der Figur dargestellten Feder 116 treten an den Armen befestigte Federn, welche die Arme so zusammengehen, daß sie einen Kegel bilden.Instead of the tilting system shown in the figure, which consists of the two arms and the There is spring 116, you can also use the tilting system train in a different way. For example, you can use a swivel head, which takes the place of the middle piece of the armature 104, in which a row is distributed around the circumference Arms are articulated. Similar to arm 106, the arms carry contacts, while one of the arms is formed like arm 107. Instead of the one shown in the figure Spring 116 occurs springs attached to the arms, which move the arms together so that that they form a cone.
